M5lp 0711 05 Z 1991 Ford Mustang Rear View

Putting the Mach 1 Four-Valve 4.6's power to the pavement is an IRS rear system from an '03 Cobra. After modifying the '91's framerails, the IRS slipped right in. Greg wants to give special thanks to Mark McDonald and DeWayne Stiles for their hard work to finish this project so well and so quickly.
